I had the "pleasure" of being overseas on business when this was enforced. No txt message to advise, just a data suspension. The help desk didn't know it was being enforced and my account rep had no idea either. I did get a link to look at the rates hours after the actual implementation but with data disabled, that is pretty useless.After finally getting the data back it was a needless nusance that we never opted into, but was regulated on us. As a business im prepaired to wear the costs as long as i can still be productive. I would have rather opted into the "data angel" option than have it enforced...........
